Titanium Series Polyester Catalyst

Antimony catalyst yog cov catalyst tshaj plaws siv hauv kev lag luam polyester tam sim no, tab sis antimony yog cov hlau hnyav, uas tau txwv los ntawm ntau lub teb chaws thiab cheeb tsam, suav nrog European Union, Tebchaws Meskas, Nyiv, thiab lwm yam. Titanium polyester catalyst yog feem ntau yuav tsis hnyav hlau catalyst los hloov antimony catalyst vim nws cov phooj ywg ib puag ncig, kev ua haujlwm siab, thiab tus nqi qis. Txij li xyoo 2004, lub koom haum Shanghai tau tsom mus rau ib puag ncig tus phooj ywg titanium polyester catalysts, thiab tau tawg los ntawm cov teeb meem ntawm kev tswj hwm kev ua ub no thiab cov qauv tsim ntawm titanium polyester catalysts, kev ua haujlwm ntawm titanium catalysts tau cuam tshuam zoo heev los ntawm matting cov neeg ua haujlwm, thiab cov txheej txheem ua kom nrawm nrawm. ntawm titanium polyester yog qeeb thiab thermal stability tsis zoo, thiab ntse tsim STlC series ntawm titanium catalysts tshiab tsim rau polyester ntau lawm. Tsim ib txhiab-tuj catalyst ntau lawm cov cuab yeej, thiab nyob rau hauv kev koom tes nrog ob peb lub lag luam, tau nyob rau hauv ib tug xov tooj ntawm cov txheej txheem ntawm peb-kub txheej txheem thiab tsib-teev txheej txheem ntawm polyester muaj cov cuab yeej ua kom tiav cov kev tiv thaiv ib puag ncig ntawm non-heavy hlau fiber ntau qib zaj duab xis. qib, lub raj mis qib polyester nti ntau lawm, thaum tsim cov txheej txheem ntawm titanium polyester catalyst formelt ncaj spinning luv fiber ntau tshuab. Peb tes num tau txais ntau tshaj 30 invention patents tso cai los ntawm Tuam Tshoj, yeej 2- khoom plig thib ob hauv SinopecTechnology Invention, 1- khoom plig thib ob ntawm Jiangsu xeev science thiab Technology Award, thiab thawj nqi zog hauv ShanghaiPudong New Area Science thiab Technology Progress Award.

STiC-01 yog ib puag ncig tus phooj ywg titanium polyester catalyst, uas yog siv los tsim cov fiber ntau thiab qib zaj duab xis polyester chips. Nws lub ntsiab nta yog raws li nram no:

◆ Ua kua, tiv taus hydrolysis, miscible nrog ethylene glycol;

◆ Tus nqi ntawm cov catalyst me me, raws li PET qhov hnyav tsis siab tshaj 5ppm titanium;

◆ Tsim nyog rau peb-kub thiab tsib-kub txheej txheem polyester ntaus ntawv, ntxiv txoj kev hloov tau yooj yim, thiab tuaj yeem muab ntxiv thaum lub sij hawm pulping lossis ua ntej pre-polymerization kettle;

◆ Cov kev ua haujlwm catalyst tsis tshua muaj kev cuam tshuam los ntawm tus neeg sawv cev matting, thiab polyester nti muaj xim zoo thiab tus nqi L siab.

STIC-B1 yog tsim rau titanium catalysts uas tsim los ntawm hotfilling lub raj mis qib slices, dej fwj, ntawv, thiab lwm yam. Nws lub ntsiab nta yog raws li nram no:

◆ Ua kua, tiv taus hydrolysis, miscible nrog ethylene glycol;

◆ High solid theem polycondensation tus nqi;

◆ Cov ntsiab lus ntawm acetaldehyde yog tsawg, xim xim zoo ib yam li cov antimony series, thiab thermal stability yog zoo.

Nrog rau kev ua haujlwm siab catalytic, PTT cov khoom siv lub teeb thiab cov khoom semi-teeb tau sim sim ntawm ib kiloton polymerization chav tsev, thiab cov viscosity ntawm PTT mus txog ntau dua 1.0dl / g.

Qhov Performance index ntawm cov xaim sib xyaw npaj los ntawm cov khoom siv no zoo ib yam li cov khoom siv txawv teb chaws.

Cov catalyst muaj kev ua haujlwm zoo hydrolysis thiab yog miscible nrog dej ntawm 90 thiab ruaj khov rau ntau tshaj 24 teev, uas daws qhov teeb meem uas cov pa catalyst n-butyl titanate (TBT) yooj yim rau hydrolyze rau hauv precipitate thaum nws ntsib dej, ua rau yeeb nkab fouling, hloov hluav taws xob cuam tshuam, thiab yuav tsum tau nres ntau lawm rau kev ntxuav. Lub viscosity thiab xim ntawm PBT hlais tau txais los ntawm kev ntsuas kev lag luam zoo ib yam li cov tau txais los ntawm TBT.

Txij li thawj cov hlau tsis muaj polyester ntau lawm hauv Suav teb xyoo 2009, ib puag ncig-phooj ywg titanium polyester catalyst tau ua tiav hauv ShanghaiPetrochemical, Yizhen chemical fiber, thiab lwm yam khoom siv polyester, hauv xyoo tas los no, kev tsim cov titanium fiber ntau, qib zaj duab xis, thiab lub raj mis qib polyester chips kaum tawm txhiab tons, txhua yam ntawm cov khoom tshiab staple fiber ntau tshaj 50,000 tons, thiab ua tiav ib tug xov tooj ntawm downstream ntau yam exported rau txawv teb chaws.
